Grubs

Over the years, viewers have watched some of their favourite celebrities chowing down on the gruesome grubs.

But bosses took action after survival expert Ray Mears argued that local tribes relied on the bugs for nutrition - and that the practice could offend them.

Ray explained: “It’s rather like someone coming to Britain and saying, ‘Eating a roast potato, isn’t that weird?’ The witchetty grub that the aboriginal people depend upon is an important source of protein.

“It has a religious significance. For us to go and make fun of that is very disrespectful.”
